SCSI
SCSI. See small computer system interface (SCSI).
SCSI object type. The Subsystem Control Facility (SCF) object type for an Open SCSI
device.
SCSI passthrough terminator. A bus-terminating plug connected between a cable and the
external connector of a customer-replaceable unit (CRU). The SCSI passthrough
terminator contains the necessary termination resistors required by the SCSI bus. See
also terminator.
SCSI plug-in card (S-PIC). A plug-in card (PIC) for the 6760 ServerNet device adapter
(ServerNet/DA) that uses a small computer system interface (SCSI) interface to
connect devices to an HP NonStop™ S-series system. See also plug-in card (PIC) and
fiber-optic plug-in card (F-PIC).
SCSI ServerNet addressable controller (S-SAC). A ServerNet addressable controller
(SAC) that is contained within a small computer system interface (SCSI) plug-in card
(S-PIC).
SCSI terminator. See terminator.
SDK. See Software Developers Kit (SDK).
SE. System engineer. See service provider.
searchList. For each loadfile, a list that is constructed and used by the linker and loader to
tell them which libraries to examine, and in which order, to locate symbol definitions
needed by that loadfile. The linker and loader construct the loadfile’s searchList in
accordance with that loadfile’s import control, which is set at link time by the loadfile’s
programmer. A loadfile’s searchList is unaffected by the import control of any other
loadfile.
SEB. See ServerNet expansion board (SEB).
SEB port. A connector on ServerNet expansion boards (SEBs) used for ServerNet links. An
SEB has six emitter-coupled logic (ECL)-based ServerNet ports. See also MSEB port.
Security Manager Process (SMP). A component of the Safeguard subsystem that
manages all changes to the subject and object databases and authenticates user
logon attempts.
segment. In general, a contiguous sequence of logically related pages of virtual memory.
The pages of the segment are individually swapped in and out of physical memory as
needed. Within a loadable object file, one of the portions of the file that is mapped as
one unit into virtual memory as the file is loaded. See also code segment and data
segment.
selectable segment. A type of logical segment formerly known as an extended data
segment. The data area for a selectable segment always begins with relative segment
